LLDP-MED Commands
The LLDP-MED commands in this section are:
• advertise med guest-voice
• advertise med guest-voice-signaling
• advertise med location-identification
• advertise med power-via-mdi
• advertise med softphone-voice
• advertise med streaming-video
• advertise med video-conferencing
• advertise med video-signaling
• advertise med voice
• advertise med voice-signaling
FTOS LLDP-MED (Media Endpoint Discovery) commands are an extension of the set of LLDP TLV
advertisement commands. The C-Series and S-Series support all commands, as indicated by these
symbols underneath the command headings:
c s
The E-Series generally supports the commands, too, as indicated by the e symbol under command
headings. However, LLDP-MED commands are more useful on the C-Series and the S50V model of
the S-Series, because they support Power over Ethernet (PoE) devices.
As defined by ANSI/TIA-1057, LLDP-MED provides organizationally specific TLVs (Type Length
Value), so that endpoint devices and network connectivity devices can advertise their characteristics
and configuration information. The Organizational Unique Identifier (OUI) for the
Telecommunications Industry Association (TIA) is 00-12-BB.
• LLDP-MED Endpoint Device—any device that is on an IEEE 802 LAN network edge, can
communicate using IP, and uses the LLDP-MED framework.
• LLDP-MED Network Connectivity Device—any device that provides access to an IEEE 802
LAN to an LLDP-MED endpoint device, and supports IEEE 802.1AB (LLDP) and TIA-1057
(LLDP-MED). The Dell Force10 system is an LLDP-MED network connectivity device.
With regard to connected endpoint devices, LLDP-MED provides network connectivity devices with
the ability to:
• manage inventory
• manage Power over Ethernet (POE)
• identify physical location
• identify network policy
